EMERG-ENCY-AXLE.

Specification of Letters Patent.

Patented Apr. 28, 1914.

Application led January 25, 1913. Serial No. 744,176.

T o all whom 'it may concern Be it known that I, CHARLES P. SNxDnR, a citizen of the United States, and ahresident .of Slatington, in the county of Lehigh and State of Pennsylvania, have invented a new and Improved Emergency-Axle, of which the following is a full, clear, and exact description.

This invention relates to machine parts and has particularreference to a means for repairing a broken shaft or axle in a siniple and reliable easily applied manner.

More definitely stated, one of the objects of this invention is to provide an emergency device or appliance adapted to be carried in the tool chest of an automobile, and so constructed that in the case of breakage of one of the driving axles, the wheel may be removed from the broken part and the emer-A gency appliance connected to the remaining part, ofthe axle, and the Wheel then connected to the emergency device'.

A further object of the invention is to provide a means coperating with the emergency device whereby it may be disconnecti ed from the broken axle when a new axle is tobe introduced and such appliance held in reserve so that it may be subsequently used in the event of another axle breakage.

The foregoing and other objects of this invention will hereinafter be more fully described and claimed and illustrated in the drawings forming a part of this specification in which like characters of reference indicate corresponding parts in the views, and

varied in accordance with the various types of machines to which the invention is applicable without departing from the spirit thereof ashereinafter claimed.

Referring more particularly to the drawings, I show at S a portion o a shaft or axle which remains after the wheel end portion thereof has been broken from it s, it being a well recognized fact that in certain types of automobile construction the vast majority of breaks in such axles occur between the wheel and the roller bearing support. i

At is shown a fragment of a Wheel having a hub 11 which is understood under normal conditions to be rigidly secured upon the outer end of the axle, namely, that portion of the axle which was broken from the main portion at s, It will hence be understood' that such portion of the axle will preferably be tapered to conform with the interior taper of said hub 11. My emergency device, therefore, comprises a spindle 12 tapered as a counterpart of said hub taper and being substantially the same size andl shape as the broken end of the axle above referred to. as an integral part of a casing 13 which will be understood as being adapted to take the.

place of the usual bearing member which ordinarily is provided with a conventional set Said spindle 12 is constructed of anti-friction rollers 14, the rollers being Y maintained in connection with the bearing in any suitable manner as, for instance, by contact with the inner surface of the shaft casing 14. This casing with the rollers 14 attached thereto and secured in place as by overlapping flanges 15 will therefore be substituted for the bearing normally used, it being understood, as before intimated, that these parts will be made interchangeable with respect to any standard type of machine. i

Another main portion of the emergency axle is a chuck 16 having any suitable number of longitudinal slits 16said chuck being externally tapered so as'to conform with the slight internal taper of the casing, as shown at 13. The interior of the chuck is adapted to receive the main portion of the broken axle which fits into the chuck with an easy but practically close fit. 'Ihe said interior face of the chuck may be knurled as shown at 17, if desired, vfor the purpose of increasing the grip thereof upon the axle. Extending outwardly from the closed end of the chuck is a shank 18 which'projects through the center of the spindle-12 and is adapted to receive any suitable means serving al dual purpose, namely to force the hub 11 upon the spindle and maintain it in such position and also to draw. the shank and chuck longitudinally of the spindle and casing, whereby the axle S is firmly gripped in place, making it, together with the spindle y,20 bearing directly against the outer end of the hub. The nut 19 may be locked in place by any suitable means, such, for instance, as

a cotter pin 21 to prevent accidental loosening of the parts. For all practical purposes, therefore, the construction just described and illustrated in Fig. 1 constitutes a complete substitute for the original axle, rc-ller bearing Ysupport and bearing rollers, togetherwith any means necessary to secure the wheel'in place upon the a-Xle or spindle.

The spindle is provided at its outer `end with a screw thread 12 which I use for the purpose o'f removing the chuck 16 from the casing 18 after the wheel has been removed from the spindle. For this purpose I employv a cap or yoke 22 havin an internal thread for coperation with vthe thread 12 aforesaid, said yoke-being provided with a hub 23 in alinement with said shank 18. A screw 24, is tapped through said hub 23 and bears against the outer end of the shank, as shown in Fig.' 2. When force'i is applied through said screw and yoke to the shank 18, the chuck will bek forcibly ejected from the casing and will therefore release its grip upon the axle S.-

Having thus described my` invention, I claim as new and desire to'secure by Letters Patent t 1. In a device of the character set forth,

the combination with a wheel hub, of a spindle to which the wheel hub is adapted to be connected, a casing for the spindle, an

axle, and means operating through said 40 spindle and casing to secure said aXle in operative relation to said spindle and wheel hub, said securing means operating also to Secure the hub upon the spindle.

2. In a device of the character set forth,

the combination lof a spindle,a bearingr support connected to said'spindle, a -chuck withinthe bearing support, a shank extending through and beyond said spindle to move c the chuck longitudinally of the bearing support, and means applied to the outer end of the spindle whereby such movement is effected.

3. In a device of the character set forth,

the combinationof a spindle, a casing conthreaded means applied to the outer end of the spindle for the purpose of forcibly moving the chuck and shank longitudinally 'of the Acasing and spindle, substantially as set forth.

In testimony whereof I have signed my` 11a-me to thisl specification in the presence of 'two subscribing witnesses.
